. METH) OF EXTRACTING OLS FROM SOLIL To all whom it may concern:

FII

Be 'it known that We, CHARLES TURNER and RICHARD F. Sonnosonn, citizensof the United States, and residents of Chicago, lcounty of Cook, andState of Illinois, have vinvented certain new and useful Improvements inthe Method of Extracting Gils from Solids,`otvvhich the following is aspecilication, and which are illustrated in the accompanying drawings,forming a part thereof.

The invention relates to that method of extracting oils from solids,such as vegeta ble or animal mattei', in Which an oil solvent isemployed, and which may include treatment of the material by hot vaporsfor thepnrpose of eliminating the volatile parts, andvparticularly forrecovering by volatili- Zation and subsequent condensation the oilsolvent which may be held in the material Vby absorption.

The obj ect of the invention is to simplify and expedite the Work and toprovide for continuous operation upon material as it moves through thezones of action. 4

The invention consists broadly in passing the material through a chztmber, or chan bers, in a practically loose and open state andintroducing into the massthe oil solvent or the heating agent, thematerial be ing impacted at the receiving and delivery ports of `suchchamber, or chambers, and thereby preventing the escape throughineseports 01E-any part of the dissolving orheatin'g agent except so muchthereof-as muy be .held by absorption.

lThe invention may be practiced by mea-ns of any apparatus which Willadvance the material through the chamber, or chambers, Within which itis to be treated, retarding` its movement as it enters and leaves suchcham ber for the purpose of impacting it iito a substantially imperviousmass and Wh' fh includes means torintroducing the solvent or heatingagent into the material at suitable stages. v p

One torni ot' apparatus suitable for practicing the improved method isillustrated in the accompanying' drawings, in which-- Figure 1,appearing in part on each ot' two sheets, shows a longitudinal, verticalsection ot' the apparatus; Fig. 2, a vertical section on the line 22'ofFig. 1; and Fig.

3, a detail in perspective ot the section ot the apparatus within whichthe material to be treated. by the'solvent or heating agent.

The apparatus shown comprises a continuous tubular cylinder throughwhich the material to be treated may be caused to travel at variablerates of speed through different sections ot the cylinder. The cylinder,as shown, comprises a receiving sec- `tion 10, into which the materialmay he introduced through a hopper 11, and which isv shown as inclosedby a jacket 12 into which steam may be introduced through a pipe 13,

for the purpose of freeing the material from moisture, the vapor. beingpermitted to escape through suitable openings; a section 11 havingforaminous Walls and receiving the material from the section 10; asection 15 receiving the material from the section 14 and passing` it onto a section 16 having foraminons Walls; and a section 17 receiving thematerial from the section 16 and beingprovided with a lateral dischargeaperture 18.

A shaft 19 is journaled in the heads of the cylinder and is located uponthe axis thereof and is provided at the end with a pulley 20 by means ofVvvhich it may be rotated. Conveyor blades 21, 22 and 23, here shown aseach formed of a continuous spiral, are

mounted upon the shaft 19 and located respectively Within the cylindersections 10, 14 a-nd`116. Choking nipples 24, 25 are preferably placedWithin the cylinder intermediate of the sections 10 and 14, and 15 and16. The delivery end ot the cylinder may be cramped by mea ns of a valve2G shown` as slidablv mounted upon the shaft 19 and controlled by a handlever 27. The cylinder sections 14 and 16 are inclosed, respectively,Within tanks 28, 29, adapted to receive liquids discharged from thematerial.

The oil solvent may be introduced into the apparatus by means of a pipe30, branching, as shown, at 31, 32, and entering the tank 28, each ofthe branch pipes 31, 32 delivering to a plurality of pipes, as 33, 34extending along the outer surface ofthe cylinder section 14: and openingintothe interior of this section throughapluralityof nipples` as 37, 38.A heating vapor, such as steam, may be introduced into the cylindersection 16 by means of a similar arrange` ment ot'r pipes, the mainsteam pipe being shown at 39 and one of its branches at 40.

i It desired, the shaft 19 may be trlbular and are included Within thecylinder sections lei and 16 are lreely perforated, as shown at fill,45. A vent pipe 4C is shown as leading from thc clnu'nher of the tank 28to the discharge pipe Il? leading from the tank 29,

A steampipe i8 is shown as entering the tank QS), and serves as means 'fordriving out any vapors which may accuinjulaie therein. pipe 49 leadsfrom the upper portion o't the tank 29 for the purpose. oi conveying'therefrom vapors which may be delivered to a suitable condenser.

finan apy'iarartus such as has been dcscribed, the material to betreated being delivered into the cylinder .section l0 is advancedtherethrough, at such speed as may be desired, but before leaving thissection is Well heated and practically freed from all water with whichit may have been charged. As it leaves the cylinder' section l() itbecomes impacted and moves slowly section lll Where it. is disintegratedand advanced more rapidly by the conveyor mechanism therein.` `WhileWithin this cylinder section and in a practically loose state, itbecomes charged with the oil solvent vintroduced through the pipe 3()and its branches, and this solve'nt with the oils are drained. throughthe apertures of tf inder Wall. into the tank 28 and com therefrom tovany suitable \receptacle. As the material issues from the cylindersection itis again retarded Within the cylinder s Walls. the l ersupplemented, when such device it nt. by the choking nipple 25, andbecomes so impacted or solidified that any vf )on which `may be presentWithin the confines ci me tanl-r 28 cannot escape therethrough, and theyare prevented from escaping into the cylinder section l0 by the impactedmass ot material between that section and the section lli. .y

As the impacted rmaterial slowly enters the cylinder se' tion 16, it isdisintegrated and more rapidly advanced through that section by theconveyer' mechanism It the vaporizing agent, preferably steam, whichisldelivercd through the pipe and its branches.y Anyc the oil solventwhich `may have beeny .heldmvithin the material by absorption is herevaporized :ion .l5-1 by the friction ot' the.

The process is not dependent upon thcparticular apl'iaratl'ls hereinshown a ud dcscribed, but may be practiced by any apparatus whichprovides 'For the continuous. or substantially continuous, inw-:cumul olthe material, its retardation and hnuaclng at cach side of the zonesWithin n 1 .rh il is to be treated hy the solvent or` vaporizing agentmuy be acrmuplishcd bv any suitable means other than ille spiralcon\'c\'cr. as. l'or example, a rcciprrwatuin' plunger. o1' (he processmay be prariticeii by the use ol au apparatus so arranged that thematerial will become impacted by gravity. The advantages oi" the processare that the operation may be continuous, and requires very littlelabor. liurthermorc, the various actions may be easily regulated byvarying` the rate of travel of the material through the apparatus andthe quantity of dissolving;` and vaporizingg' agents uscd. The residueof thc solid material is discharged as a part of the.

process and without suspending` the operation.

While thc described method, so far as wc are at present advised, may bemosteconomically and advantageously practiced by givlin@ the material acontinuous niovcmentfthc invention is, however, of suiiicient scope toinclude an operation in which the material 'may be allowed to como torest.
